摘要
从Ｂ样条曲线一阶导数公式出发，推导了非均匀Ｂ样条曲面、ＮＵＲＢＳ曲面单位法矢量的计算公式，并进行了实例验证，为复杂自由曲面数控加工系统设计以及刀具与工件相对运动轨迹的模拟奠定了基础。
On the basis of the first order derivative equation of B Spline presented by the BOOL, this paper explored the normal unit vector non uniform non rational B Spline surface and NURBS surface.The calculation paradigm have also been presented. This work has established the foundation for the design of NC systems and the simulation of the relative movement of cutting tool to workpiece.
